The soil residual activity of Milestone herbicide is what provides more than a few days’ worth of weed control. By contrast, 2,4-D controls some weeds that have emerged, but 2,4-D does little to control weed seedlings that emerge days later.
In the soil
The active ingredient aminopyralid in Milestone both broadens the spectrum of control and provides soil residual activity to control susceptible weeds that germinate for several weeks after spraying.
Over the season, the active ingredient breaks down and its soil residual activity dissipates. But enough may remain for the next two to three years to damage extremely sensitive crops if Milestone ends up in cropland. Don’t plant a broadleaf crop until an adequately sensitive field bioassay shows the crop won’t be affected, Dow AgroSciences recommends.
In the plant
While the herbicide is still active in the soil, grasses may absorb and store the active ingredient, so it may be present in hay harvested from treated grass for up to 18 months after treatment. Treated grass hay should never be used, sold or given away for mulch or compost. Enough aminopyralid could leach from the hay to damage sensitive broadleaf plants. Likewise, don’t feed treated hay on land to be planted to sensitive crops.
Through the animal
When a grazing animal ingests treated grass or grass hay carrying aminopyralid residue, the residue passes through without harm to the animal. But the active ingredient may be present in the manure or urine for three days after consuming the treated forage. For that reason, manure from animals that have consumed grass or hay treated with aminopyralid should be used only on permanent grass
pasture. Don’t spread it on cropland or provide it to others for gardening purposes. Spread the manure on permanent pastures only.
County Highway Construction will begin this week with Central Specialties, Inc moving in to pave the bituminous overlays in the eastern part of the county. These bituminous overlays will take approximately 4 weeks. Motorists can expect slight delays due to pilot cars and flagging but the roads will remain open to traffic during paving. Other Lyon County Construction:
Cottonwood Main St and Minneota 4th St final paving - Late May
Township Box Culverts - Fall
Camden Bridges - Fall/Winter ’17 and Summer ‘18
ROAD AND BRIDGE CAPITAL IMPROVEMENT PLAN
Adopt -A- Highway is a public service program for volunteers to pick up litter along Lyon County’s highways. It’s a way for environmentally conscious citizens to make a personal contribution to a cleaner environment.
How Does it Work?
Community groups, churches or businesses adopt a highway by picking up litter on both sides of the highway for at least two years. Lyon County will help your group select a highway to adopt. Roads that have heavy traffic or are inaccessible to pedestrians will not be eligible. Your group’s representative will sign an agreement on behalf of your group. All participants must review the safety information provided by Lyon County before every pickup. Participants must be 12 years old, unless specifically permitted. Participants 18 years old or younger must have adequate adult supervision. Groups shall arrange pickup dates in advance with the Lyon County Highway Department. Work may not be allowed on or near holidays. Groups shall leave filled trash bags along the roadside as specified by the Lyon County Highway Department. Groups are encouraged to recycle materials for their own benefit. Adopt -A- Highway groups agree to adopt a highway for a minimum of two years, select a segment of highway at least 2 miles in length, Pick up litter at least 3 times a year and deposit filled bags at the nearest highway shop. Lyon County agrees to provide high visibility vests, trashbags and safety information, remove large, heavy or hazardous items, erect a highway sign to recognize your group’s cleanup efforts. If you’d like to adopt a highway, call the Lyon County Highway Department at (507) 532-8205
